Frequency/Digital outputs
The meter has three user-configurable selections for configuring either a Frequency output or
Digital output (FODO).
Digital output (FODO).
•
FODO1 (four possible parameter configurations)
•
FODO2 (eight possible parameter configurations)
•
FODO3 (eight possible parameter configurations)
Frequency or Digital Outputs (FODO 1) source
•
FO1A, DO1A, FO1B, DO1B
•
Frequency output 1A is based on frequency content (Actual - Uncorrected Flow Rate)
•
Frequency output 1B is based on frequency content and Frequency 1 B Phase
•
Digital output 1A is based on Digital output1A content (Frequency1A Validity or Flow
Direction)
Direction)
Frequency or Digital Outputs (FODO 2) source
•
FO1A, DO1A, FO1B, DO1B, FO2A, DO2A, FO2B, DO2B
•
Frequency output 1A is based on frequency content (Actual - Uncorrected Flow Rate)
•
Frequency output 1B is based on frequency content and Frequency 1B Phase
•
Frequency output 2A is based on frequency content (Actual - Uncorrected Flow Rate)
•
Frequency output 2B is based on frequency content and Frequency 2B Phase
